测量仪器

This instrument generated the sine wave signal which frequency could change in three situations. The sine wave signal inputted to the buffer amplifier, then divided into two groups, a group connected with oscilloscope to survey the peak-to-peak value of fundamental wave, another group connected with wave trap to filter out the fundamental wave, then the oscilloscope was used to survey the various sub-harmonics amplitude of the output.

该仪器是通过设计可变三种频率的正弦波信号发生器产生的正弦波信号，其输出信号经过缓冲放大器，输入放大器后分为两路，一路接入示波器，测量基波幅值；另一路接入陷波器将基波滤去，再用示波器测量其输出各次谐波幅值。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
